- field devices are always used, which use process sensors to determine process variables using sensors or control controlled variables using actuators. These corresponding field devices determine and / or regulate, for example, the pressure, the flow rate, the level, the temperature or a different physical and / or chemical process variable as a process variable in a process flow.
- Applicants have produced and distributed such field devices under the name of, for example, Cerabar, Deltabar, Deltapilot, Promass, Levelflex, Micropilot, Prosonic, Soliphant, Liquiphant, and Easytemp, which are primarily intended to contain at least one of the above-identified process variables of a medium in a container to determine and / or monitor.
- a common feature of all measurement or field devices mentioned above is that a measured value is determined and evaluated from the process variables determined by the sensors by means of a downstream device electronics.
- This device electronics is usually adapted to the corresponding measurement requirements and the process variable to be measured so that independent device electronics must be developed for each sensor principle, for each process variable to be measured and for each measurement performance.
- Another solution is, for example, to equip field devices of different measurement accuracy standards with a uniform device electronics and with a maximum measurement performance and to activate or deactivate the individual functionalities eg by software.
- this has the disadvantage that due to the equipment of the field device with the maximum performance and the maximum storage space for the program and the data must be available and the device electronics must already contain all expansion electronics, which is very expensive.
- Another way to increase the functionality of a basic, standardized device electronics can be done by adding an expansion electronics.
- a disadvantage of increasing the functionality of the entire field device through these expansion electronics is that the programs of the field device with a new, adapted to the expansion electronics version of an operating program or firmware must be overwritten and here the maximum memory size for the program and the data in advance for Must be available.
- Performance and functionality can be easily adapted to the requirements and can be realized cost-effectively.
- the expansion card includes at least one on the memory space of the expansion program designed second memory unit, that an automatic detection of the connected expansion card is provided by the base map, and that for the expansion of the basic program by the corresponding expansion programs a partial and / or temporary access of the arithmetic unit is provided on the second memory unit.
- an expansion electronics is provided on the expansion card.
- the first memory unit is constructed from a first data memory and a first program memory.
- Field device provides that the second memory unit is constructed from a second data memory and / or a second program memory.
- an address decoder for addressing the individual addressable memory areas of the data memory and program memory is provided.
- the data memory and program memory are in fixed predefined memory areas of the arithmetic unit.
- an identification at defined positions of the program memory of the first memory unit, and / or the program memory of the second memory unit is provided.
- a supplementary embodiment of the field device according to the invention allows for the automatic detection of the connection of an expansion card to the basemap a recurrent electronic query of the individual expansion card is provided.
- Fig. 2 shows an embodiment of the modular invention
- Fig. 4 shows a memory allocation
- Fig. 5 shows a locking mechanism of the expansion cards.
- a field device 1 is shown according to the prior art, the device electronics consists of a basemap 2, which is designed by an expansion card 3 modular expandable.
- the field device 1 is, for example, a measuring device of the process automation technology with a sensor that determines a physical process variable.
- a sensor or sensor is a technical element which certain physical or chemical process variables, such.
- B. the level, flow, pressure, the pH, the temperature, the humidity, the conductivity as the electrical quantity M quantitatively determined.
- These process variables are detected by the sensors by means of physical or chemical effects and converted into a proportional, further processable, electrical measured quantity.
- the Felellaelektronik on the base map 2 includes, for example, a signal conditioning unit that linearizes the amplified measurement signal, amplified, scaled and / or calibrated.
- the field device 1 comprises an actuator or actuator which influences a physical or chemical process variable in a process via a controlled variable.
- a field device 1 The process automation technology communicates via a two-wire connection cable or a fieldbus with other field devices or a higher-level control center according to eg 4-20 mA current, Profibus PA, FF or HART standard. Furthermore, the field device can be supplied with the necessary energy via the fieldbus.
- the field device has a field device electronics with mostly a computing unit 4 and a microcontroller.
- This field device electronics of the field device 1 is designed, for example, on a printed circuit board 14 at least as a base map 2.
- the base card 2 of the field device 1 comprises at least one arithmetic unit 4, an address decoder 10 and a first memory unit 6, which are interconnected via data lines.
- the memory unit 6 consists of a first data memory 8a for storing data and a first program memory 9a for permanent storage of a basic program.
- the basic program contained in the first program memory 9a is read out and processed by the arithmetic unit 4 via the address decoder 10.
- the data and intermediate results resulting from the execution of the basic program are stored in the first data memory 8a.
- This basic program comprises only the basic functionalities of the field device 1, so that the field device 1 has the basic functions such as e.g. can perform the control of the field device 1 and the execution of the basic measurement function.
- the basic program that is stored in the first program memory 8a of the base card 2 may be replaced. This can be done on the one hand by an exchange of the base card 2, which contains the old basic program, with a new base card 2, which contains a basic program extended by the program parts or on the other hand by overwriting the first program memory 8a with a basic program extended by these program parts.
- the operator of the field device 1 must either replace the entire field device 1 and the base card 2 of the field device 1 or after expanding the base card 2 by an expansion card 3 a completely new Import basic program or a new firmware in the first program memory 8a.
- This first program memory 8a is designed, for example, as a flash memory, an EPROM or an EEPROM, which nowadays can also be integrated directly in the arithmetic unit 4 or a microcontroller.
- a second memory unit 7 is integrated on the expansion card 3, which stores a second data memory 8b for the volatile storage of further data and intermediate values from a calculation of the arithmetic unit 4 and a second program memory 9b for permanent storage of the expansion program containing the supplementary program parts of the basic program, includes.
- the expansion card thus not only includes the additional hardware in the form of expansion electronics 5, such as an A / D converter, a controller, a microprocessor, a digital signal processor, a temperature sensor and other sensors or actuators, which may be necessary for the extended functionality but also the required expansion of memory and programs.
- the expansion card also contains an additional second data memory 8b as main memory, so that the maximum required working memory does not have to be kept unused on the base card 3, but is available exactly on the expansion card 3 according to the requirements of the expansion programs.
- the expansion card 3 includes the missing program parts for function expansion and the necessary working memory in the form of a second data memory 8b completed.
- the second data memory 8b and the second program memory 9b of the second memory unit 7 are addressed by the arithmetic unit 4 via the address decoder 10. If an external expansion card 3 is detected and activated, for example, by a mode switchover, the arithmetic unit 4 executes the additional functionality of the expansion program, which is stored in the second program memory 9b of the expansion card 3.
- the expansion card 3 is connected via a standardized interface 12 with the base card 2. At least one expansion card 3 can be electrically connected to a base card 2 via this interface 12.
- the interface 12 is designed as a rack system in which the base card 2 and the expansion card 3 are inserted via guide rails in the rack system and connected via a plug connection to the parallel bus system.
- the external functions F e of the expansion program in the second program memory 9b of the external expansion card 3 are integrated into the functional sequence of the basic program in the first program memory according to a program sequence list available in the arithmetic unit 4. This integration takes place, for example, by calling and executing the individual functions F e of the expansion program or the individual functions F 1 , F 2 of the basic program via the address decoder 10 by the arithmetic unit 4 in accordance with this program sequence list.
- the field device 1 is, for example, a
- Level measuring device which determines a level in a process by means of which a pump control is to be carried out on a pump.
- the field device 1 with the base card 2 includes, for example, the basic program with the first function F 1 for level measurement and the second function F 2 for communicating a measured value via the fieldbus.
- an external function F e is still required, which includes a controller that calculates a corresponding control value for the pump from the measured value of the level.
- This external function F e is according to the invention in the second Program memory 9b on the expansion card, so that this additional functionality for pump control can be integrated by connecting an expansion card 3 with a basemap 2 in the basic functionality of the field device.
- this second program memory 9b could, for example, as shown in FIG. 4, be displayed on previously defined memory areas via the address decoder 10 in the address area of the arithmetic unit 4.
- a unique identifier 11 e.g. a memory address may be used, which is located at the beginning of the respective memory area and allows a unique identification of the expansion program.
- Expansion programs are distributed to the different memory units 6 and 7, so-called global program flow lists must be created, which control the logical program flow. Further attention must be paid to further information, such as parameter addresses, menu structures and texts of a local display, since these are now also distributed in the second memory units 7 on the expansion cards 3 and the first memory unit 6 of the base card 2.
- the handling of this distributed information takes place, for example, in the following manner, such that when initializing a field device 1 consisting of a base map 2 and at least one expansion card 3, by means of an initialization routine, a one-part, global list in the main memory consisting of at least the first data memory 8a and / or at least one second data memory 8b exists, is created and distributed information is summarized so.
- the field device 1 must recognize that changes to the programs and / or the field device electronics are to be performed, whereby the field device 1 transitions into a basic functionality of the basic program, in which no access is made to the external second data memory 8b or second program memory 9b. This prevents data and program errors due to incorrect, inconsistent or incomplete data sets when installing or removing the expansion cards. If the change or expansion of the programs and / or the field device electronics is completed, then the additionally existing functionality on the expansion card 3 can be put into operation.
- the individual printed circuit boards 14 are equipped for connecting the signal lines with connecting pieces 16, such as spring strips. At the end of the last printed circuit board 14, an end piece 15 is mounted, which shorts two wires and thus indicates the correct assembly. If an expansion card 3 or the end piece 16, for example for mounting another expansion card 3, removed, the short-circuit connection is interrupted and by this change request, the field device 1 goes into its basic functionality. In the basic functionality, the field device 1 only executes the basic program of the first program memory 8a on the base card 2. Another way to display a change request would be, for example, expansion cards 3, which are inserted into a rack system. These rack systems generally have individual slots in which each expansion card 3 and / or base card 2 are locked by means of a locking mechanism. This locking mechanism can simultaneously serve as an electrical switch signaling a change request. LIST OF REFERENCE NUMBERS
